Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = , this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is , this is the equation for population data as we can't calculate these
and
as we take these values as given and also we do testing for
parameter using t test and it is sure that testing is always done on population data not on sample data.
Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game = minutes,
Also, the time for each level of game is minutes,
If there are l levels of games,
Then the time taken in all levels of game =
Hence, the total time ( in minutes ) = Set up time + time in all level
=
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
Which is the required inequality.
Option 'B' is correct.
